comment multivariate lognormal distribution in mathematica
Well, no ... there is not just one parameterisation of the Lognormal distribution. There is not even 1 notation for the 'Normal distribution': most define it as $N(\mu, \sigma^2)$; but some people use $N(\mu, \sigma)$. Your question is undefined ... you need to link your multiLognormal to a parent multivariate Normal (which you will need to define), or specify the pdf of your desired multi-Lognormal yourself.

comment multivariate lognormal distribution in mathematica
But you have failed to specify the functional form of the pdf as (a) intended by yourself, (b) as implemented in R, and (c) implemented in Mma. How are we to know that (a), (b) and (c) happen to be all the same?

comment How to find a function result from expectations functions
And have you tried adding assumptions on the parameters, as suggested in the previous questions? And what happens when you do so? And why does your question contain all that numerical clutter, if you are interested in a symbolic answer anyway?

What's the question? How is this different to: mathematica.stackexchange.com/questions/67567/… and mathematica.stackexchange.com/questions/67627/…

comment Infinite sums with Boole and EvenQ
???? Sum[x/x!, {x, 2, Infinity, 2}] has always been part of the question. Maybe you missed it?

comment Mathematica displays the unevaluated expression Expectation function
(i) I think you are looking for trouble by using notation like o*l which can easily be mis-read. (ii) Add Assumptions -> {r >0, etc} will help solve symbolic problems. (iii) Use NExpectation for numerical problems (given numerical parameter values): otherwise keep things symbolic.

comment Mixture / Hierarchical Distribution from Conditional
Where is it conditional? Where does Y appear on the RHS of X|Y ~ Poisson(Z)?

comment Generating Random Real numbers with certain numbers not included
My fear is that the OP has little sense about what he is asking.

comment Generating Random Real numbers with certain numbers not included
There are two possibilities: (i) if the OP wishes to avoid exact integer 3 (as the question currently states), then there is no problem, theoretically or practically, as you seem to understand. (ii) If the OP wishes to avoid real 3.0 (which is a different question to that posed by the OP, but perhaps his intention), then the solution is to catch them (with whatever desired tolerance) and remove them.

The OP's question specifies his aversion to the integer 3, not 3.0. I cannot say if he intends something else.

No idea whether it work ... but I do not believe it is necessary. Just using RandomReal should be just fine.
